Title: Laser gas discharge apparatus
Inventor: CLARK GRAEME LAWRENCE
IPC: H01S3/0975
Filed: 1987-05-13
Abstract: Laser apparatus includes a wire 8 helically wound about a quartz laser discharge tube 1. During operation of the laser apparatus, a discharge is established between an anode 4 and cathode 5 by closing thyratron switch 7 to cause heating and vaporization of copper bromide powder 13 within the tube 1. Then double pulse operation is initiated, in which a first pulse of microwave energy is transmitted along the wire 8 to establish a discharge within the tube which causes the copper bromide to dissociate into copper and bromine. A second pulse of electrical energy then causes a conventional discharge to be established between the anode and cathode electrodes 4 and 5, resulting in excitation of the dissociated parts of the compound. Laser radiation results as the dissociated elements return to their lower energy states. <IMAGE>

Title: Asymmetric screw threaded devices
Inventor: MATSUSHIMA RYOTARO
IPC: F16B39/30
Filed: 1989-03-31
Abstract: To prevent loosening of screws due to bending of screw threads 15, 17 at the time of tightening so producing only line contact between the threads, the screw threads 15, 17 having the same nominal diameter but having mutually different bending strengths of their screw threads 15, 17 because of different dimensions or materials of the screw threads 15, 17, the width of the gap between the flanks of the screw threads 15, 17 is made to increase progressively towards the member of lower bending strength, by cutting away part of a thread flank (e.g. 15b). As shown, the nut 16 and bolt 14 are of the same material, and the bending strength of the bolt thread 15 is less than that of the nut thread 17 because the base of the bolt thread 15 has a smaller axial extent. Instead of the cutting away of the bolt thread 15 at 15b, the nut thread flank 17a may be cut away. <IMAGE>

Title: Generation of fine bubbles
Inventor: BHAGAT PHIROZ MANECK
IPC: C02F3/20
Filed: 1989-06-15

Abstract: A punch press for deep-drawing operation has two vertically spaced crankshaft cam mechanisms 4, 5, Fig.1, an upper slide 6 driven by the upper crankshaft cam mechanism 4 to move up and down, and a lower slide assembly 7 including spaced apart slides 74a-74d capable of vertical reciprocation at different time intervals when driven by the lower crankshaft cam mechanism 5 through a set of push rods 76a-76d. A bed 8 is fixed by its lower part above the upper part of the lower slide assembly 7 to be directly opposed to the movable upper slide 6 which carries an upper die 9A in alignment with a lower die 9B carried by the fixed bed 8. The punch press, in a single action stroke, is capable of accomplishing a series of processes such as blanking, multi-stage deep drawing trimming, shaping and stripping on a workpiece W held between the dies 9A, 9B. Each process involves the use of stamping dies 97a-97d Fig.5(B), connected by push rods 99a-99d to respective ones of the slides 74a-74d. Trimming is effected by co-operation of die 97c and cutting die 95. A punch pin 98 effects final forming of the workpiece W. <IMAGE>

Title: Apparatus for recovering dry food from packages
Inventor: EARP JOHN
IPC: B65B69/00
Filed: 1990-03-21
Abstract: Apparatus for recovering the dried food content of packages comprises an input 11, conveying means 14 for feeding the packages to a treatment station 15, an apertured guide surface 18 at the treatment station, and a rotary drum 21 arranged at the treatment station and having circumferentially spaced beating blocks 22 for engaging each package and for driving the package and its contents along a guide path defined in part by the guide surface 18 such that a block impacts a package as it enters the guide path to thereby expel the food content of the package and serves also to convey the package material along the guide path. Food discharge openings 20 in the guide surface 18 permit the gravity and/or forced discharge of the expelled food during movement of the packages along the guide path, and means is provided for collecting the food falling from the discharge openings, as well as from an apertured collector surface 24 receiving the packaging material issuing from the guide path. A fan 25 is arranged so as to direct a stream of air to the downstream end of the guide path, to assist in the discharge of the packaging material from the guide path to the collector surface 24. In a modified embodiment, Figs 3-6 (not shown), packages are fed in by a chute, and an exhaust duct is used to suck away packaging material. A product-receiving conveyor has larger apertures downstream of product-discharge apertures so that sachets of flavourings contained with a package of a product can be separated. <IMAGE>

Title: Process and apparatus for forming the edge flange of containers of synthetic thermoplastic material
Inventor: PADOVANI PIETRO
IPC: B29D/
Filed: 1990-08-02
Abstract: According to the apparatus of the invention, beaker container blanks (27) of at least one continuously delivered stack, are engaged at an outturned flange region and delivered axially in sequence between successive threads of a circumferentially spaced set of heated rollers (22, 22', 22''). The blanks having heated flanges are sequentially delivered by air blasts into the edge rounding cavities of female moulds (49), disposed around a plate (40) which sequentially rotates through stations; at which the rim is rounded between the female mould cavity and an axially displaced male mould (50); at which the beaker is ejected by means (51) from the mould (49) into a stack (34); and at which the moulds (49) are cooled. According to the process of the invention, heat damage to the blanks within the heated delivery rollers is avoided during stoppage of rounding, by mounting the rollers (22, 22', 22''), for displacement about a pivot (52) out of alignment with the female moulds, so that blank delivery is not interrupted. <IMAGE>

Filed: 1991-02-12
Abstract: A game machine for coins or tokens has a rotating flat horizontal playfield 2 which rotates about axis 4 in the direction of arrow A beneath a peripheral wall 15 formed by an array of vertical rods 16. Coins C are delivered to the playfield 2 through chutes 20 to be carried by the playfield into abutment with the end 15a of the wall and thereafter moved in abutment along the wall. The wall 15 is of spiral form with respect of the axis 4 so that the coins moving along the wall are displaced progressively towards the centre of the playfield. An aperture 22 is provided in the playfield and when sufficient coins are deposited on the playfield and displaced in abutment with each other towards the aperture 22, coins can fall through the aperture for collection as winnings by a player. Located in the wall 15 is an opening 30 through which a proportion of coins on the playfield can pass to move off the playfield and fall through an opening 31 to a collection station inaccessible by the player. Risers can be provided in the playfield surface and adjacent to the aperture 22 to cause stacks of coins to develop and possibly overhang the aperture 22 during their displacement over the playfield. <IMAGE>
